GEORGE D. WILKINSON, OF OAK PARK, ILLINOIS, ASSIGNOR TO CRIBBEN & SEXTON COMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

y OvEN THERMOMETER.

Application led August 15, 1921.

To all 'whomt may concern.'

Be it known that I, GEORGE D. lVinKiN- SON, a citizen ofthe United States, residing at Oak Park, in the county of Cook, State of Illinois, having invented certain new and useful Improvements in Oven Thermometers, do hereby declare that the following 1s a full, clear, and exact description of the same.'

My-invention relates to devices for indicating the temperatures of ovens 1n cooking stoves or ranges, and consists'in the novel and useful constructions herein described in any suitable manner,

and then pointed out in the appended claims.

InV the accompanying drawings, which illustrate a practical embodiment of my present invention and in which the same reference numerals indicate similar parts in the different figures, Fig. 1 is a view in front elevation of a gas stove with part of the open-top broken away and the Ovendoor jamb of the front frame provided with a thermometer for ascertaining the temperatures in the oven heated by an oven-burnerl of any suitable form or type; y

Fig. 2 is a detail sectional View on the line 2 2 of Fig. l on an enlarged scale, and

Fig. 3 is a detail vieu7 on the line 3 3 Fi". l.

s shown the reference numeral 1 indicates the frame of the gas-range or stove, 2 A

the open-top cooking section, and 3 the oven section arranged at one side of the open-top and having an upper baking oven and a lower broiling andv toasting oven separated from each other by the usual sheet-metal partition. Below the partition the oven burner is suitably arranged and supported, and is connected to the gas-manifold of the burner-box of the top cooking sectionV in any suitable manner now well-known in the art. The front-frame or door jamb 4 of the ovensection, to which the doors 5 and 6 -of the upper and lower ovens are suitably pivoted, is attached to the sides 7 of the oven section and the oven is provided at each side with a lining 8 and a rackplate 9 having the usual guides or ways and forming the heat-circulating flues l0 and dead-air spaces or chambers 11. The iues Serial No. 492,233.

jamb is provided on its front face with a countersunk seat l2 in which is located a thermometei 13 of either the liquid or metallic type with its liquid chamber or thermal element, as the case may be, vextended rearwardly through the jamb and entering the corresponding heat-.flue forming part of the oven area. In the form shown the instrument is a mercurial thermometer having its dial or indicating leg carried on a frame 14 and its heat-responding leg l5 carrying the mercury bulb bent at a right angle thereto and passing through the jamb into the heat- Hue -10 ofthe oven. By this arrangement the thermometer is located at a'point where its indications arein plain view, while it is set into the stove-frame so that it does not project above the frame orbeyond the line of its front face and is protected against injury and breakage. Also, the heat-responding leg in the flue-space is protected by the rackplate 9 against injury by pans ywhen the latter are placed in the, oven. It is conveniently located, easily read and out of the way, while it indicates the temperatures of the oven so that the burner may be regulated to afford the desired degree of heat in the oven for cooking` 'di'erent articles of food. Its location on the jamb enables it to extend back into the cooking area and so give the temperatures at that point, and to be used on either low-down stoves or cabinet ranges.

I claim:

1. A stove having an oven, a front frame for the oven having a countersunk seat, and a thermometer mounted in the seatgo the front-frame and having its heat-responding leg extending through said frame and located in the oven.

2. A stove having an oven provided with lateral heat-iues, a front-frame for the oven having a countersunk seat, and a thermometer mounted in the seat of the front-frame and having its heat-responding leg extending through 4said frame into the oven.

3. A stove having an oven provided with lateral heat ues, a front-frame on the oven, one of the vertical members of the frame having a countersunk seat in its front face, and a thermometer located in said seat and having its heat-responding leg extending rearwardly through the frame into one of the heat iu'es.

In testimony whereof I- aix ature.
